The part comes in a 16-VFQFN with exposed pad (supplier package 16-VQFN, 4x3.5 mm), surface-mount only. FRAM gives you non-volatile storage that writes at near-SRAM speed with essentially unlimited endurance—no wear-leveling needed for frequent data logging or configuration updates. ## FRAM vs Flash — the endurance and write-speed advantage Unlike conventional Flash-based MCUs, the FRAM program memory in this MSP430 handles write cycles orders of magnitude beyond typical Flash endurance—no sector-erase penalty, no wear-leveling firmware overhead. For a design that logs sensor data or updates calibration constants every cycle, FRAM eliminates the write-latency and endurance ceiling that Flash imposes. The 3.75 KB size suits small control loops, state machines, or communication protocol stacks where code fits in a few kilobytes. For procurement, this part is a safe BOM commitment—no last-time-buy clock ticking, no forced redesign window. ## Peripheral set and connectivity for sensor and interface nodes The 8-channel 10-bit ADC handles analog inputs like temperature, pressure, or battery voltage monitoring without an external converter.","metaTitle":"TI MSP430FR2311IRGYR 16-bit MCU, 16 MHz, 3.75 KB FRAM","metaDescription":"Texas Instruments MSP430FR2311IRGYR 16-bit MCU with 16 MHz core, 3.75 KB FRAM, 1 KB SRAM, 12 I/O, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"12","Core Processor":"MSP430 CPU16","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2311","Program Memory Size":"3.75KB (3.75K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"16-VQFN (4x3.5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f54bef595f6c353e931fcbdbed65c27e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430FR2311IRGYR and MSP430FR2311IRGER?","answer":"The difference is in the packaging and reel format. The IRGYR suffix typically indicates a different tape-and-reel quantity or reel size compared to the IRGER variant. Both share the same die, memory size (3.75 KB FRAM, 1 KB SRAM), 16 MHz speed, and 16-VQFN package. For exact reel dimensions and quantities, compare the specific reel specifications on the order page."},{"question":"What is the closest pin-compatible alternative to MSP430FR2311IRGYR?","answer":"Within the MSP430 FRAM family, the MSP430FR2311 is the base product number. Pin-compatible siblings with different memory sizes (e.g., MSP430FR2111 with smaller FRAM) share the same 16-VQFN footprint and peripheral set. For a direct drop-in with more memory, check the MSP430FR2422 or MSP430FR2433 in the same package—verify the pinout against the datasheet before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR2311IRGYR","citationPolicyUrl":"https://icboms.com/llms.txt","lastUpdated":"2026-07-17T19:50:00.618Z","lastPublished":"2026-07-17T19:50:00.618Z","indexable":true}}
